Grand Marais is situated on the shores of Lake Superior. The lake's massive size and surface area affect the air pressure. The lake cools the air in summer and warms it in winter. This temperature regulation impacts the atmospheric pressure.
The surrounding terrain is a mix of forests and hills. These features can disrupt air masses, leading to changes in pressure. The nearby mountains also influence the flow of air and pressure patterns.
In winter, cold air from Canada moves southward over the lake. This leads to a decrease in pressure. In summer, warm air from the south moves northward, increasing pressure. These seasonal changes influence the local weather patterns.
